Fix several inconsistencies in these drivers WRT reporting the clocks:

- when using DPLL mode, 'pata_hpt37x' driver reported the DPLL frequency as the
  PCI clock -- make it properly report both clocks and add the same ability to
  the 'pata_hpt3x2n' driver;

- both drivers sometimes use "pata_hpt3*:" and sometimes "hpt3*:" in the
  messages -- make them use only the former one;

- the message about failed DPLL stablizatios deserves KERN_ERR and a bang. :-)
